PROBLEM TO BE SOLVED: To provide a liquid crystal display device which is arbitrarily changeable over to a wide visual field angle characteristic and a narrow visual field angle characteristic according to a use form. SOLUTION: The liquid crystal element 19 for phase difference control of the liquid crystal display device including at least a liquid crystal element 10 for display and the liquid crystal element 19 for phase difference control consists of the constitution of any among, firstly, cholesteric liquid crystals 15 or chiral nematic liquid crystals 15 which are held between substrates 11 and 18 having electrodes 12 to 17 on the inside surfaces and are subjected to planar alignment or, secondly, the nematic liquid crystals 15 which are held between the substrates 11 and 18 having electrodes the 12 to 17 on the inside surfaces, are isotropic at the time of using the liquid crystal display device and are perpendicularly aligned by voltage impression or, thirdly, the nematic liquid crystals 15 which are held between the substrates 11 and 18 having the electrodes 12 to 17 on the inside surfaces and are randomly aligned. |
